The deepest diving mammals – TOP 10

The deepest diving mammals

Until recently, the record belonged to the sperm whale, a little earlier to the elephant seal. In March 2014, a group of researchers from the Cascadia Research Collective, led by Gregory Schorr, discovered that one of the Cuvier’s beaked whales, monitored by them, was diving at a record depth of 2,992 m (9,816 ft). Another Cuvier’s beaked whale broke a record of being underwater, belonging to the Elephant seal – it remained below the surface of the water for 2 hours and 18 minutes.

The Cuvier’s beaked whales are therefore record-holders in terms of diving depth and underwater dwell time.
